Shopper's Paradise & Shopper's Paradise HD

I've been looking for different games to try and I've noticed Shoppers's Paradise HD has been in the top paid section for a while, costing $2.99. I was all set to get this until I came across Shopper's Paradise for $4.99. They appear to be made by the same company, SecondGear. Does anyone know what the difference is between the two? Is one an android app?
